If serviceImpl is pointing to wrong service in @Service annotation, error
message should point out to exact problem with serviceImpl/service/operation
-------------------------------------------------------------------------------------------------------------------------------------------------------
Key: TUSCANY-1517
URL: https://issues.apache.org/jira/browse/TUSCANY-1517
Project: Tuscany
Issue Type: Bug
Components: Java SCA Problem Determination
Reporter: Rashmi Hunt
If user makes error in service impl, pointing to a wrong service interface
in @Service annotation, during composite startup, Tuscany tries to introspect
the
impl and tries to match to service operation and fails with below exception.
Even though it's user error, with this exception message, user can not
figure out what is the problem with the composite. Exception message should be
clear
enough to point to exact error with details about which
serviceImpl/service/operation.
Example serviceimpl for this defect
@Service(HelloWorld3Service.class)
public class HelloWorldImpl implements HelloWorldService {
....
}
